Answer:
C. Equally likely
Step-by-step explanation:
1/2=0.5=50% probability
12+2x-10=3x-5
12-10 +2x=3x-5
2+2x=3x-5
Move +3x to the other side. Sign changes from +3x to -3x.
2+2x-3x=3x-3x-5
2+2x-3x=-5
2-x=-5
Move +2 to the other side. Sign changes from +2 to -2.
2-2-x=-5-2
-x=-7
Multiply by -1 for -x and -7
(-1)(-x)=(-1)(-7)
x=7
Answer: x=7
1 because if you were to get h rn e measure of the problem right here it would be a cosine of 1
1. -7 + 9= -9 + 7 is false
2. Is 4x - 3 = 19 is open, because this could be a valid equation.
3. 16 = 4x - 4
So, 16+4=4x; 4x=20; x=20/4; x=5..... option C is the correct one.
4. length of the classroom is 2.4 times its width.
given length = 42 in, and since length = 2.4 times width, width = 42/2.4,
hence option A) 17.5 in is correct
5. x - 3 = 10
x = 10+3 =13
Option B is the right one.
